I _think_ you are talking about the color of the fan clutch that holds the fan to the water pump pulley. This is a consumable part that might have been replaced already, and they can be found in a variety of colors on eBay. I can't imagine why anybody would care about the color of the fan clutch, but since they can be had in colors for the same price as black, I suppose it doesn't really matter.
I would not guess that a fan clutch would have been replaced already, but it could have. I would not worry ...
I had a question about a pink colored part in the 6 cylinder engine of a
>2006 DC SR5. Found a 2006 with 18000 miles at a good deal around $20k.
